Turbo Upgrades for the GUIV TD42Ti

[mudski]

I will tell you Darren that fan will be useless if you dont modify the clutch fan. I have the same fan, and have done some tests over the last month or so with my own Patrol. The new fan with a stock hub changed nothing. Adding a tube and a half of oil made slight changes, the hub was locking in slightly earlier, assisting is reducing temps quicker. I have recently added another 18ml, one bottle, and now the hub is locked totally. Temps today, being cold outside were lower again, the water temps actually dropped when the car was moving and rose when stationary. Which it never did before. The only issue now is the fan noise. Im not so sure i will be able to put up with it. But i want to see how it goes in real heat at 110ks, this is where my kettle would see 115c. I think i will remove about 10ml from the hub next to see the results.
This is from my own findings mate. I am sure results will vary from motor to motor.

Hi Matty.

Are they any pros or cons running wastegate reference from inlet manifold area as opposed to compressor?

Guessing it's true pressure going in?

Yeah closer to whats actually going into the engine.

So went over to JPC today and grabbed one of their hi spec water pumps. Looks the biz!!



Then stopped in at MTQ and grabbed an Oil Drain flange and pipe. Glad I did! eBay was $45 plus post. MTQ was $24 pickup. Happy days



Note the part number of anyone is chasing one.

Did you get the oil return hose as well?

Why the cooling system mods?

Hi mate, no I will try and get to Pirtek tomorrow if I get time. My company has a big account so should get s good price.

Taking the opportunity to sort out my cooling while the coolant is dumped. It has always ran hot when towing and on the beach. Obviously the turbo will sort most of that out but I see the benefit of the water pump. The engine has done 270k so I'm ok to swap out the water pump regardless.

I agree with Matty getting that hose Dazz. I got a standard hose from Pirtek and it wasn't great.

I got Andy to put on a Flexi hose but Mattys one would be good if you can.

About $170

About $100 to much

Both. Alway bounce off the top end of my Pyros but the water temp rises to hot on a big long hill climb towing and on the beach.

Ok. What is the condition of the current equipment? I have never really had engine cooling issues apart from an externally blocked core but have always maintained my cooling system well. Do you still have that rubbish egr hooked up?
